Specification of Letters Patent. Patented Sept, 25, 191% Application filed Juncl', 1914.. Serial No.-'842,231.

To all whom it may concern:

Be it known that I, LoUIs A. HAWTHORNE,- a citizen of the United States, and resident of Newark, in the county of Essex, State of New Jersey, have invented new and useful Improvements in Metal-Punching Machines, of which the following is a specification. v

The invention relates to machines for punching structural shapes and more especially to devices for successively traveling and stopping the beams or shapes in definite and. accurate relation to the punching devices so as to accurately locate the punches for the rivet holes in the beam or shape. Objects of the invention are to provide for accurate and rapid successive traveling and stopping of the shape relatively to the punching means, and especially in connection with heavy shapes and beams; to provide means for effecting this under the control of automatic distance record devices; to pro vide novel devices and mechanism for the purposes indicated; to provide selectively operated means for. the purposes stated wherein any desired distances including denominations and fractions thereof within all requirements of commercial usage may be set without duplication or multiplying the machine parts, and independently of the rate of travel of the work; to provide novel forms of mechanism for effecting these results and objects; to effect other objects and functions necessary or desirable in such a machine. These and other objects of invention will in part be obvious, and in part will be set forth hereinafter.

The invention consists in the novel-parts, constructions, arrangements, combinations and improvements, herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention, and together with the description serve to explain the principles thereof.

Referring to the accompanying drawings, illustrating by wayof example one embodiment of the invention, means are provided for progressing or traveling and successively stopping the beam or shape in correct position with reference to the punching mechanisms to be punched thereby. In the embodied form of such means, the beam or shape 00 rests upon driven rollers 1, arranged in a series horizontally and driven in a suitable manner. Saidv rollers 1 have fixed to their shafts beveled ears 2 with which mesh beveled pinions 3 xed upon the shaft 4. Shaft 4 has fixedv thereto a gear 5 driven by a pinion 6 on the shaft of'a motor 7. For convenience two sets of driving mechanisms may be provided at either side, respectively, of the punching devices.

The punching devices are indicated generally by a portion of their frame or 110118. ing 8 and 9, and are shown two in number, arranged in series or tandem along the path of travel of the shape. The mechanism just described is generally similar to that shown and described in copending application, SerialNumber 814,380 filed January 26, 1914:, of-T. P. Payne. It will be understood, however,-that so far as concerns many features mining devices. The rolls 1 maybe continutherefrom by connections from the distance determining means, the travelland stopping of thebeam thus being permissive and controlled byithe setting-:oftherdistance deterously or intermittentlydriven as desired,*s'o far as concerns inany features of'the invention. i

In accordance-with certain features of the invention, ahead or member is provided v travelingwith and controlling the travel of the shape and adapted to selectively engage with -:a plurality of engaging members or dc vices,'=located.alongthepath oftravel of the shape, and spaced apart proportionately to or in accordance with, distance units, as for instance, lineal feet of travel of thesshape along its path. The invention in certain of its aspects provides also *for further movement of the head and the engaging devices afterthey have passed into engagementrwith each other to complete the desired-or selected distance of travel. Thus, the travelin integral feet may be determined by the'engagement of the head and a particular one of the spaced apart engaging devices and their movement together-after passing into engagement will elfe ct'the inches and fractions of additional travel necessary toicomplete the full distance reading or amount of travel.-'

T-he *embodied' form" of machine has been arranged to operate inaccordancewith the foot and inch system. In said embodiment, astationaryuguide member 15 is arranged horizontallyalong the path of travel of the beam or shape, extending on both sidespast the locationof the-punching mechanisms 8 and-' 9. 'The'guide member 15is provided with a fiat upper bearing surface 16 and projecting or shouldered edges 17 and 18, and is supported upon-suitable supports 19. Traveling along the pathway of'the beam or shape 00 and along the guide 15 is a head25 which engages with the shape, and has connectionsto the distancedetermining means whereby the shape is stopped or permitted to travel in correspondence withthesettings orindications of the distance determining means,

As embodied, the head 25 has abearing or engaging'surface 26 against which the forward end ofthe shape 00 abuts, and'by which.

the shape .is .held from travel when positioned and stopped" for punching. The head 25 rests upon the face -16 of the guide 15 and has K downwardly extending side pieces 27"and1"28, which vterminate, respect1vely,-:1n

inwardly pro]eoting flanges or walls 29 and 30 fitting about and embracing the shoulders 17 and 18 of the-guide 15, and thus firmly and-accurately hold-ingthe head 25 to the guide 15 while permitting it to slide or travel therealong.

Extending along the guideway or member' 15 is a screw threaded shaft'40 having a longitudinal; adjustments later described-in I detail.

Means :are provided by the invention for causing or permitting a'set or predetermined free. travel of the head25- and for then causing the head 25 and screw shaft 40 to engage together'sothat thehead 25- can then move ,only with the rotation of screw shaft 40. The head is; traveled andstopped thereby accurately :and nicely at; the set or predetermined distance. -Means are also provided for; permitting such :relative travel of the head .25 and screw shaft 40 fora desired predetermined distance asset by the distance record i device.

In accordance with certain featuresof the inventionalso, the free travel of the head 25 relatively-to; the shaft40 corresponds to the amount of travel inone distance denomination' whiletheamount of travel-inanother distance denomination is effected orallowed for by the combined movement of the shaft 40 and the headx25 when in engagement with each-other. In the embodied form, the travel in feet is effected with the head 25 traveling out of engagement with the shaft 40,-and the inches and sixteenths-ofsan-inch of travel required over and above an integral'foot is effected by andthroughthe rotation of the shaft 40 While the head 25 is in engagement I therewith;

In the embodied form of means, the de-v vices for causing theheadi25 to engage with ordisengage from the shaft 40 are controlled froma distancerecord device, and by means of electrically operating connections. The head.25 is-semicircu-larly recessed as at 43 tofit about'the part 'ofithe shaft 40 projecting above the surface 16 of the guide- .way 15,'the head and the guideway thus completely encircling the shaft 40. Within I thread.

engaging member 45 is in engagement with the thread on shaft 40, travel of the head 25 in proportion to the rotation of the screw shaft 40 only is permitted. Each turn of the screw thread about shaft 45 thus constitutes an embodiment of an engaging member or device regularly spaced along the path of travel of the shape and head, the head being adapted to pass selectively into engagement with any desired turn of the screw The translational travel of the head 25 is thus proportional to and is controlled by the rotational movement of the shaft 40.

For causing and controlling the movements of the engaging member 45, as embodied, there is mounted in horizontal apertures in the head 25 and above the screw shaft 40 a reciprocable bar 51, which bar also passes through slots in the engaging piece 45, which slots permit relative trans verse movement between the rod 51 and piece 45. Pivotally connected to the bar 51 and to the reciprocating engaging piece 45 are links 52 so proportioned that the movement ofthe bar 51 will dran the piece 45 out of engagement with the shaft 40 or press the piece into engagement with the shaft. To the reciprocating bar "51 is attached the core 58 of a solenoid 54, which solenoid is carried upon the front of the head 25. Operating also upon thesolenoid core 53 is a spring 55 in compression between a bracket 57 and the head of a rod 56, attached to the solenoid core 53. \Vhen the solenoid is deenergized, the spring 55 decenters the core and forces the bar 51 to the right (from the position shown in Fig. 6 to that shown in Fig. 5) lifting the screw threads of the engaging member 45 out of engagement with the screw threads of the shaft 40 and thus leaving the head 25 free to travel unconnected from the shaft 40. When the solenoid 54 is energized, it moves the bar 51 against the spring 55 and forces the screw thread of the engaging member 45 into engagement with the screw thread on the shaft 40 as shown in Fig. 6.

In accordance with one feature of the invention, said means comprises a plurality of actuating devices for the engaging device 45, said actuating devices being spaced proportionately along the .path of travel of the head 25, and settable means for rendering such actuating devices operative or inoperative to cause the engaging device to engage the screw shaft.

In the embodied form, as stated, the distance determining means or control for the shape traveling and stopping devices is electrical and also is controlled from a distance record sheet. A contact carrying rail 60 extends above and along the guideway 15, said rail being suitably supported as by angled or bent arms 58, mounted upon the guideway structure. In the rail 60 at fixed distances, and preferably one foot apart, are contact pieces 61 insulated from the rail 60. Carried by the head 25 in circuit with the solenoid 54is a shoe 62, which slides along the under side of the rail 60 and successively passes into and out of contact with the contacts 61 set into the under surface of the rail 60. Also in circuit with the solenoid 54 is a trolley contact 63, which travels along a wire 64, in circuit with the solenoid 54. A battery or other suitable source of electrical energy is indicated by 65.

In accordance with one feature of the invention, and for the purpose of simplifying the connections, a double make and brake, one controlling the units of feet and the other controlling the tens of feet is em ployed. There are ten circuits representing ten groups of units of feet, and a particular unit of feet in each denomination of tens is in parallel in said circuit with that particular unit in each of the other denominations of tens. One make and break in the circuit is for the purpose of designating'the particular unit of feet and the other make or break is for the purpose of designating or determining in which denomination of tens of feet such unit designation shall become operative. As embodied, the second make and break is employed to kill the circuit in each denomination of tens of lower value than the selected or pre-determined one, by throwing such portion of the circuit open or dead. By way of example, each key for two feet, namely, two, twelve, twenty-two etc, are in parallel, the circuit including a bus wire 65. Said. bus wire has switches 163 and 164 therein controlling the tens of feet, namely, zero tens of feet (the units), tens of feet, twenties of feet, etc. 1

Considering these as controlled by the distance record sheet 68 (Fig. 11) the closed contacts 66 may be regarded as energizing the selected unit of feet, and as putting under potential such unit in every ten feet along the rail 60. The contacts 67 may be regarded as controlling the tens of feet. lVhen the contacts 67 are permitted to close by the presence of a perforation in the distance record sheet 68, the solenoid 69 is energized to open the circuit at 164. The shape is traveling from right to left in Fig. 11. The opening of the circuit at 164 will render. the contacts 61 which correspond to the contact 66 at the right of the point 164 dead, while such contact 61 in every ten feet to the left thereof is alive. The shoe 62 will thus pass every contact 61 in the given circuit which is to the right of 164 without result but when the first contact 61 to the left of 164 is reached, the solenoid 54 is energized, and the engaging piece 45 engages the screwrod 40.-

Beferring now-to the means for control- I tionary plate 89.

ling the ultimate or finer divisions of the set or selected distances or measurements (in this embodiment the inches and frac tion thereof), the screw shaft 40 (Fig. 1) has an extension fixed to rotate therewith and provided with a friction drive 76 of suitable form. :Beyond the .friction drive 76 is a shaft 77 carrying a gearv 78. Gear 78 is driven by a pinion 79 on the shaft of a. motor 80. The motor 80 through the friction clutch 76v tends-to drive the shaft 75, and means are provided forpermitting or preventing such rotation ofthe shaft 75 andof the shaft 40 to effect the desired travel ofinches-and fraction thereof. As embodied, therev is fixed on the shaft 75 a pinion 81 meshing with a disk 82 having gear teeth thereon. Geared disk 82 is fixed on'shaft. 83, said shaft being supported in bearings 84 and 85. The. geared disk 82 has in face contact therewith a disk 86 (Figs. 1, 7, 8, 9 and 10), said disk 86 being splined on a sleeve 87. Fixed to sleeve 87 is a disk'88. Disk 88 is in face contact with a stationary plate 89,-which carries the bearing of shaft 83. In the disk 86 is an arcuate slot 90. In alinement with said slot 90 and reciprocable in apertures in the rotatable disk 86 are a series of pins 91, projectable into and retractable from the slot 90. Each of said pins is provided with a solenoid. 92 to the core 93 of which the corresponding'pin 91 is attached. Each pin 91 is provided with a retracting spring 94, and a ring 95 serves-as a stop for the retracted solenoid cores.

In the disk 88 are a series of slots 100, and projectable into and retractable from said slots area series of pins 101 reciprocably carried in apertures in the sta- The pins '101 are connected with the cores 1030f the solenoids 102. Said solenoids have retracting springs 104,-:and the plate 105 serves as a stop for the retracted cores-103. To'the disk 88is connected -an--arm'106,-said arm 106 being acted .on by asuitable restoring spring 107. Thus accurate'means for effecting the location of the shape in conformity with the ultimate or finer divisions of the set distance issecured, the disk 86 accurately determining the inches and disk 89 the sixteenths-of-an-inch.

The various solenoids 92 and 102 are in circuit with contacts 108 and "109 (Fig. 11) in the distance record sheet 68. In circuit withthe shoe '62 is a trolley 115, said trolley running in contact with a wire 116, in circuit with which is. a solenoid 117. Said solenoid 117 controls the circuit for the motor 80 which drives the screw shaft 40.

iMeans are provided for longitudinally adjusting the screw rod 40-to secure nice and accurate positioning of the shape relatively to the punches. Fixed'to the rod 40 is a ring or collar 120 -workingagainst a face 121 upon the bearing 42. Thebearing 42-is sli'dable upon its supports-122, and is adjustable by screws 123, 124, 125 and 126, threaded into capped lugs 127 and 128, 1 29 and-1 30 fixed on the support 122. Thus nice and. accurate longitudinal adjustment of the screw shaft 40 is secured. The thrust up by the bearing 42 the wire134. The wire 134 isin circuit with the solenoid 135 controlling a make and break 136 for the roll driving motor '7 or for a controller for 'said motor, either beingindicated. by reference numeral 7 in Fig. 11. v

Themanner of. operation of the various devices will be clearly understood from the various statements already given in connection with the various devices, but it may be stated by way Ofsummary:

The distance-record sheet 68 may be regarded as presenting a certain distance reading or indication, and the rollers 1 may be regarded asbeing in rotation having been started into motion either automatically by the punching mechanism on completing the previous punching, or by the distance record sheet, or if desired, manually by an operator.

As the shape. Jo-travels, the shoes 62 and 132 slide'along the under side of the rail 60 andpast the various contacts 61 in succession. The selected contact 61 for the units of feet is' energized by reason of the setting made by the perforations in the distance record sheet 68. .vVhen the shoe 132, which is in advance of the shoe 62 contacts with the energized contact 61, the circuit is closed, the solenoid 135 is energized, its switch is moved from the neutral or high speed posi tion, and the circuit at 136 is controlled to first slow down the drive of the rolls 1 and then to stop them. The shoe 62 meets the i shaft 75, and the shaft 10 through friction drive 76, the rotation of shafts 40 and 75 being controlled by the settable pins on disks 86 and 89.

The distance record sheet 68 has also set the selected contacts 108 and 109 corresponding'to the inches and fractions of the desired distance, as called for by the perforations in the sheet 68. The contacts 108 and 109, through solenoids 92 and 102, set the corresponding pins 91 and 101,'thus' leaving the shaft 40 free to rotate. Through such rotation, the pinion 81 rotates the geared disk 82, and such rotation continues until the set pin 91, which is stationary, contacts with the end of the slot 90. When this'occurs the disk 86, sleeve 87, and disk 88 start into rotation, and rotate until the set pin 101 reaches the end of its slot 100.

By reason of the member 45 having threaded engagement with the screw thread of shaft 40, there will be an additional advance of the head 25 corresponding to the inches and sixteenths-of-an-inoh setting of the mechanism just described. I

The punching mechanism may be started as follows: When solenoid 135 opens at 136 the circuit for the shape forwarding rolls, 1, it throws past the neutral position and closes the punch startin circuit at 137. In series with the switch 13! is a' similar switch 138 closed by solenoid 117, when the control motor circuit is opened at 108. In the same circuit are contacts 139 working through a perforation in the distance record sheet 68, which indicates the punch or tool which it is desired to operate. When the punch start ing circuit is closed at all three points, 137, 138 and 139 a closed circuit obtains which energizes the solenoid 14.0 releasing the stop motion of the punch, permitting it to perform its work. It will be noted that the punch cannot operate until both driving motors for the shape forwarding rolls, 1, and also the control motor have stopped, bringing the shape :0 to rest in proper position relative to the punches.

The punching mechanism is called into operation to punch the positioned shape, and it may be called into operation, automatically by connections controlled by the distance record sheet or by the parts controlled thereby. The distance record sheet will also be fed forward automatically in a suitable manner and by suitable means, such for instance as that shown in the copending application already referred to, and thus the successive travelings and 'positionings and punchings of the beams be effected. I

From all the foregoing it will be under stood that a machine has been provided embodying the objects and advantages herein set forth, together with other objects and advantages. It will also be understood that changes may be made from the particular mechanisms shown and described, within the scope of the accompanying claims, without departing from the principles of the invention, and without sacrificing its chief advantages.
